[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information input device and a microphone with the information input device.

[0002]

2. Description of the Related Art In recent years, some information devices such as computers have a built-in function of reproducing music. As an example, a CD-ROM that can play music on a computer
Some have a built-in drive and treat the computer like a CD player by running the control software for the CD-ROM drive on the computer. As a further development, built-in music CD-RO
There is also something that can be imported from M and processed. Such a computer processes music as follows. First, music reproduced from the built-in CD-ROM drive is converted into digital data by A / D conversion, and this is stored in a memory or a hard disk. The stored data is processed and edited, and then stored again in the memory or hard disk. When the stored data is D / A converted and output from a speaker or the like, the processed music is played back from the computer.

Karaoke can be considered as an application of these computers. For example, karaoke is realized by putting a CD containing karaoke music on the built-in CD-ROM drive, controlling the CD-ROM drive from the computer, and singing into the microphone connected to the amplifier built into the computer. . At this time, operations such as start and stop of music are performed by operating the software for controlling the CD-ROM drive.

[0004] Karaoke can be performed in the following manner by using a computer which can take in music from a built-in CD-ROM and process it. First, music data containing a song is loaded into a memory or a hard disk, and by processing this, music data with the song erased is created and saved. Next, the stored data is reproduced. At this time, if the cycle of D / A conversion of the reproduction data is made different from the A / D conversion cycle at the time of capturing music, the key of the reproduction music can be changed. By programming these series of operations as karaoke reproduction software, a karaoke function by a computer can be realized. By operating the above software, it becomes possible to enjoy karaoke singing into a microphone connected to an amplifier built into the computer in accordance with the music being played. At this time, in order to perform operations such as start, stop, and key control of music reproduction, it is necessary to operate the karaoke reproduction software running on the computer. Another use of computers is as a presentation tool. This is a method of using a computer screen instead of an overhead projector (hereinafter abbreviated as OHP) to give a presentation at a place such as a presentation. In this case, the screen of the computer is displayed using a large-sized display or the like, and at the same time, the voice is made louder by using a microphone and an amplifier to explain to the listener. The presenter speaks the explanation contents into the microphone, and at the same time, switches the display contents of the computer screen according to the progress of the explanation.

The operation of the karaoke system using the present invention will be described below. First, the CD-ROM drive device l
Set the music CD to 3 and CD-ROM drive 1
Start 3 The microprocessor 11 selects the input port 7 as a data input destination. CD-
The music data reproduced from the ROM drive device 13 is input to the microprocessor 11. The microprocessor 11 writes the input music data in the memory 14 and stores it. Next, the microprocessor creates music data for karaoke by calculating the music data in the memory. The music data for karaoke is performed by deleting the voice included in the music data. It is known that the sound is deleted by obtaining the difference between the right channel and the left channel of the stereo music signal.

Further, the music data is processed according to the preference of the user. For example, the equalizing process is performed by performing a filter calculation. The music data for karaoke created in this way is stored in the memory l4.
As described above, several music signals are loaded into the memory l4.

Next, the operation of the karaoke system when actually performing karaoke will be described. A menu is shown on the screen of the display 12 as shown in FIG. Here, the user operates the trackball device 56 built in the microphone 51 to move the pointer 15 onto the music selection button 16 indicating the music to be sung. At the same time, the microprocessor 11 judges the operation of the trackball device 55 from the input port 6 and moves the pointer 15 displayed on the display l2. Next, the user presses the push button switch 56. The microprocessor 11 judges that the push button switch 56 has been pressed from the input port 6 and the position where the pointer 15 is present, and starts playing the music corresponding to this. In addition, the user hears the sound being played and selects a key. The selection of the key is also performed by operating the trackball device 55. That is, the pointer 15 is moved onto the key selection button 18 indicating the height of the key on the screen, and the push button switch 56 is pushed. The microprocessor 11 stores the value of the selected key in the memory 14.

First of all, the microprocessor 11 has a memory 14
Read more music data. Here, the key selected by the user is read from the memory 14, and if the key is high, the D / A conversion cycle of the D / A converter 8 is set to CD.
If the value is shorter than the sample period of, and the key is low, D /
The D / A cycle of the A converter 8 is set to a value longer than the CD sampling cycle. At the same time, the A / D conversion cycle of the A / D converter 5 is also set to the same value as the conversion cycle of the D / A converter 8. Next, the digitally converted voice input from the A / D converter 5 is read.

Next, it is checked whether or not the push button switch 56 is pushed. Push button switch 56
When is pressed, the position of the pointer 15 is determined, and when it is confirmed that the position of the pointer 15 is on the effect pattern 17, a predetermined effect processing calculation is performed on the data read from the A / D converter 5. I do. If the position of the pointer 15 is on the stop button, the performance is stopped. If the push button switch 53 is not pushed, no processing is performed on the data read from the A / D converter 5. Next, the microprocessor 11
When the data from the / D converter 5 or the effect processing operation is performed, the operation result is added to the music data read from the memory and the result is output to the D / A converter 8.

The D / A converter 8 converts the input data into an analog signal and outputs it to the amplifier 9. Amplifier 9
Drives the speaker 10 by amplifying the power of the input signal.

By continuously performing the above processing,
The music and the voice of the user are mixed and played from the speaker 10. At the same time, the user can freely select karaoke start, stop, song selection, voice effect on / off, etc. by operating only the microphone without operating the mouse or keyboard.
